Product Announcement from Berg W.M., Inc.

Information Transmitting Coupling

Berg's Information Transmitting Coupling series offer zero backlash and high torsional rigidity. They are ideal for precision positioning applications where constant velocity is required for accurate feedback control.

The single piece Beamed couplings are offered in single, three and six beam design to offer engineers the largest design criteria available. They are manufactured in stainless steel, aluminum and Delrin.

We also carry Wafer Spring, bellows and sleeve couplings within this group. This product line is also available in metric sizes.

Shock Absorbing Couplings

The Shock Absorbing Coupling series, as a result of flexible plastic members connecting their hubs, dampen vibrations and shock loads as well as electrically insulates shafting.

The series is maintenance-free and quiet running with no moving parts.

The neo-flex model is available in pin hub and clamp hub style. 1" Angular misalignment (maximum), .005 shaft misalignment (maximum).

Misalignment Couplings

The sliding center element of the Misalignment Coupling series compensates for lateral and angular misalignment caused by tolerance buildup or as a result of mounting. They are corrosion resistant, and require no lubrication.

Also available in metric sizes.

High Misalignment Couplings

The High Misalignment Coupling series allows the designer to have shafts that are intentionally offset, laterally or angularly, by a large amount.

The Power Drive cores are designed to transmit rotary motion continuously in one direction of operation. The flexible shaft is constructed of quality high carbon wire and wound on the most modern automatic winding machines.

Precisely controlled stress relieving is utilized to provide optimum flexibility and smoothness. The range of maximum parallel misalignment can be from as little as .063 to as much as 3.770. Also available in metric sizes.
